Most likely, the motherboard has a poor quality reference crystal. Things like excessive heat can exacerbate the condition. Basically, the crystal does not always generate a consistent signal, so the clock can't keep track of how much time has gone by.
pluged into my laptop where else would it be?
I would use my laptop to check emails and such, and the battery, and well, nothing really I wouldn't USE my battery for anything except running my laptop which it already does on its own...
A laptop battery can be charged while using it, but it would not be likely to become overcharged when the laptop is in use, unless the laptop goes into a sleep or dormant state.
That is a comparison question. There are some really good deals on laptop batteries on eBay, and there are also really good prices on laptops almost everywhere you look. I would say in compare them, and depending on the age of your laptop if there is a $100-$200 difference in price between a battery and a new laptop, and you can afford it, a new laptop would make economic sense. I would also look and see if I purchased another battery at the time of the new laptop purchase,,if they would give you a deal on a extra battery also!
Laptop batteries have a life expectancy of approximately 400-500 recharges, depending on the battery. To conserve battery power, simply decrease screen brightness and unplug the charger when the laptop is fully charged.
Perfectly fine i would recommend it.
Laptop batteries have a finite lifespan. A laptop batter which is more than a year old may have less than half as much storage capacity.I would not buy a used laptop battery unless it was extremely inexpensive, and then only if I already had a battery i could depend on (would use the other as a backup)
All batteries will drain a small amount, even if they are not being used. However, a substantial battery drain would be due to a problem with the battery or laptop. Make sure that the laptop is indeed off, though. With Vista, clicking the power button in the start menu will not shut down the laptop, but will instead put it into sleep mode. This continues to drain the battery. Some of the lights on the computer will still be lit when the laptop is in sleep mode, while no lights will be on if the laptop is turned off.
No. The only thing would be the clock and radio.
your battery would wear out faster than normal
This should not damage the laptop at all, they are designed to be turned on at any time. (Unless of course the battery is dead.)
A laptop is designed to be portable, which is why a laptop has an internal battery. Laptops can also be powered using a cable plugged into the mains. This power cable is also used to recharge the battery. One advantage of the internal battery in a laptop is, if there is a sudden power outage, the battery will continue to power the laptop until the battery runs down. In a power outage, a desktop computer would simply stop working.
